[en] The AMS-02 experiment has been installed on the International Space Station on May 19, 2011. The main goals of the experiment are the search for antimatter and dark matter and an high-precision measurement of the spectra of the cosmic rays in the GeV to TeV energy range. This article describes the different components of the detector and presents the performances obtained at the last test beams.
[en] The electromagnetic calorimeter for the Belle-II detector is briefly described. The algorithm of reconstruction of amplitude and time of calorimeter signals is described. The status of preparation of the electromagnetic calorimeter for the data-taking is presented.
[en] The use of radiometric calorimeters in a glovebox environment requires that special consideration be given to instrument design, measurement methodology, and measurement control. The measurement system described in this paper consists of five radiometric calorimeters installed in production facility glovebox lines at Mound, a US Department of Energy contractor-operated facility
[en] The thesis is organised as follows: chapter 1 introduces the basic concepts of calorimetry in high energy physics; chapters 2-5 are devoted to the ATLAS EMEC calorimeter; chapters 6-7 deal with the ZEUS FPC; finally chapter 8 compares the performance of the two calorimeters
[en] Several types of measurements and equipment were reviewed for the Can MC and A design basis. The measurements and equipment selected were included in the draft System Design Description. Based on the SDD review, the original gamma measurement equipment was changed from a CZT based system to a HPGE system. The current design includes dry calorimeters, HPGE gamma detection system, and scales. This document will briefly discuss the selection of each instrument
[en] For laser megajoule (LMJ) facility, an accurate procedure for laser pulse energy measurement is a crucial requirement. In this study, the influence of measurement procedure on LMJ calorimeter uncertainty is experimentally and numerically investigated. To this end, a 3D thermal model is developed and two experimental techniques are implemented. The metrological characteristics of both techniques are presented. As a first step, the model is validated by comparing numerical and experimental results. Then, the influence of a large number of parameters considered as likely uncertainty sources on calorimeter response is investigated: wavelength, pulse duration, ambient temperature, laser beam diameter…. The post processing technique procedure is also examined. The paper provides some of the parameters required to allow a robust and efficient calibration procedure to be produced.
